Whoever is getting this job, make sure to work with something other than Moment.JS. Even though it still usable, it recently got into legacy mode. (It’s not really smart to start a project with a legacy plugin)
There are newer libraries that do a better job than moment.js when we talk about good practices and functional programming. https://date-fns.org/ is a good option
I assume you are storing dates in UTC but Webflow should provide the ability to have users view dates in their own time zone. At the VERY least you should provide a PST or EST at the end of the date format display options.
Is there a support ticket for this sort of functionality?
